Every year, Flighstats, an aviation insights company puts together a list of airlines with best on-time performances. Throughout the year, the company keeps a track of delays and cancellation patterns of airlines worldwide.

The list pegged KLM Royal Dutch Airlines as the "best on-time performing airline". 

However, the list also features 10 worst-performing airlines in the world. EI AI Israel Airlines was ranked the worst airline on the on-time performance front, while Air India ranked third in the list, Bloomberg reported. 

Jim Hetzel, vice-president of aviation and distribution at FlightStats, told agency that compiling the list is a herculean task. "We stitch data together from 500 different sources".

The company parses flight-tracking and positional services, airport runway times, radar services, airline data records among various other sources to come up with the lists.
